2017 MIRC Update Washington Mint
Convention Yakima, WA
December 5, 2017
2017 Review
• Research Highlights • Variety Improvement • Pest Management • Flavor/Fragrance Sensory • Considerations
• Pesticide Registrations • IR-4 • Washington D.C.
Varietal Improvement
• Which genes are responsible for:
• Oil yield • Desirable oil properties • Verticillium wilt
• Found genome sequence for SAF2
• Made crosses • M.longifolia x M.suaveolens
Multi-State Weed Research
• Pyridate efficacy on broadleaf weeds • Washington, Oregon, California, Indiana,
Wisconsin • Compared to currently registered • Crop safety with tank mixes • Regional specific weeds and soils • All mints evaluated
Entomology
Mites • Testing new miticides • Evaluating new miticides
on beneficial mites • Evaluating residual
activity of miticides • Evaluating miticide
resistance • Developing methods to
predict resistance
Pyrethroids • Testing pyrethroids
performance • Evaluating impact on
beneficials • Evaluating resulting pest
response • Data supporting progress
toward registration
Verticillium
• Developed and optimized qPCR test to detect Verticllium in fields
• Correlation with traditional methods • Greater sensitivity • Quicker analysis
• Ground truth in commercial mint fields • Positive correlation • Some unexplained variation will lead to research
modeling
Nematodes
• Evaluating new nematicides
• Northern root-knot & Pin nematodes
• Fresh & dry weights, oil content, nematode cts.
• Trends are favorable
Mint Scent vs. Pain Tolerance
• Investigate effects of Peppermint, Scotch and Native Spearmint
• Pain perception and tolerance, physiology, mood and alertness
• Peppermint and Native Sp. resulted in greater pain tolerance than Scotch
• Intended to support potential new uses
Research – Points of Concern
• Retirements / Succession Planning • Dr. Steve Weller retirement – July 2017 • Dr. Rick Boydston retirement – March 2018 • Dr. Saad Hafez pending retirement?
• Irrigation / water use research • Distillation advances • What topics are needing addressed?
Pesticide Report
Tough Herbicide
Tough Herbicide
• Section 18 granted • July 13, 2017
• Feedback • Approval timing • Availability • Apply earlier for better
control • PHI too long • Market value • State inclusions
Tough
Tough Herbicide
• Current status • Belchim Crop Protection • Section 3 has been requested • Projecting full registration in 2019
• 2018 • Section 18 request for re-authorization • In progress • Goal is earlier approval
“Tough” Pre-Harvest Interval
• PHI is 49 days • Need to be shorter • 40 days? • Working with IR-4 and
registrant • Fixable
• “Paperwork” argument • New residue study
Vydate
• Vydate® • Vydate L – Delayed to Jan/Feb 2018 • Generics available
• Return™ from Rotam Chemical Co. • Others?
Herbicides Coming Soon
• Spartan (sulfentrazone) • Double-cut addition • Expecting approval April 2018
• Zidua (pyroxasulfone)
• Pre-emergence herbicide • Dormant application • Possible approval March 2018
Warrior Insecticide
• 2018 IR-4 research priority for mint • Syngenta supportive • Dr. Walsh, WSU data supporting • EPA pyrethroid reg. review could be challenge • 2022 projected registration
• Very early in process • Registration review will influence
Sharpen Herbicide
• BASF requesting more data • Moving target:
• 2017 – 2x rate crop safety • 2018 – 3x rate crop safety
• MIRC Weeds Team • 2018 proposal to conduct Sharpen studies • Dormant application • Midwest will revise timing to fit
IR-4 Report • Critical to mint pesticide registrations • Food Use Workshop – Denver, CO • Priority Request: lambda-cyhalothrin
• Warrior™ insecticide • Pyrethroid
• Crop Group – Mint is rep crop • CLC efforts in D.C.
Washington D.C. – July 2017
• USDA-NIFA (National Institute of Food and Agriculture) • IR-4 funding challenges • Tactical Sciences Initiative
• USDA-OPMP (Office of Pest Management Policy) • Pesticide policy and regulation
• US EPA • Congressional offices
